Mayener Basaltlava
Mayener Basaltlava is an approx. 200,000 year old volcanic rock, which was formed by the cooling of the magma of the Bellerberg volcano. Due to its typical porosity, Mayener Basaltlava (Mayen basaltic lava) was already discovered and used as an ideal material for the production of millstones and rubbing stones from 6,000 - 5,000 B.C.
Today, thanks to its excellent structural-physical characteristics, Mayener Basaltlava is used as a material for cladding, stairs and flooring, wall copings and other structural elements. It is also suitable for the implementation of artistic stone cutter and sculptor work. Mayener Basaltlava also plays an important role in gardening and landscaping, the making of gravestones and as a frost protection material in underground engineering.
Frost/de-icing salt resistance as well as a high level of non-slip safety and wear resistance are only a few of the excellent characteristics of this natural stone. The structure and colour shades of basaltic lava, depending on the surface treatment from dark grey to light grey, offer architects a first-class contrast material to other building materials.
